Support commit signing with SSH key

[julius-boettger]

Description

I would like to be able to sign commits using an SSH key, which is possible since Git 2.34.0.

Motivation

I use SSH key authentication for Git, which makes it natural to also want to use this for commit signing.

I am already doing this using the command line for GitHub (following this guide) and would like to do it using JGit too, mainly because I like to use Gitnuro, which uses JGit. There's an an issue over at Gitnuro for this too.

Alternatives considered

I have considered...

• not signing my commits at all
• signing them with GPG instead

Additional context

Same issue here.

Cause

java.lang.IllegalArgumentException: Invalid value: gpg.format=ssh
        at org.eclipse.jgit.lib.DefaultTypedConfigGetter.getEnum(DefaultTypedConfigGetter.java:103)

所以这个问题解决了吗？我直接使用username and password 去commit的时候 会产生 not authorized的问题

[tomaswolf]

I've pushed a series of Gerrit commits that implement SSH signing in JGit.

Commits are merged; the feature will be in JGit 7.1.
